ADJUSTABLE BRACKET.

T o all 'whom it may concern:

Be it known that I, ANTHONY VANDER- vnLD, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Adjustable Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in adjustable brackets and its object is to provide a sheet metal structure that can be cheaply manufactured; that will be substantial and durable, and to provide the same with various new and useful features hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings in which Figure l is a side elevation of a device embodying my invention; Fig. 2 a front elevation of the same; F ig. 3 an enlarged perspective detail of the bracket; Fig. 4 an enlarged vertical section in detail; and Fig. 5 the same shown in rear elevation.

Like numbers refer to like parts in all of the figures.

1 represents a channel bar formed preferably from sheet metal, having its middle portion provided with a series of T-slots or openings, spaced apart at regular intervals, in any two of which the bracket may be inserted and supported.

8 represents the bracket of sheet metal having a vertically extended inner end to engage the face of the channel bar, said end being provided with lugs 4 to extend through the vertical portion of the T-slots and horizontally turned opposite extensions 5 on the lugs adapted to pass through the horizont-al portion of the T-slots and thence downward to firmly engage the inner surface of the front portion of the channel bar l. These extensions being turned oppositely, eifectually prevent the bracket from swinging laterally and the end of the bracket which engages the face of the channel bar is Speccaton of Letters Patent.

provided with inclined surfaces 6 which serve to force or wedge these extensions 5 firmly against the inner surface of the channel bar and thus securely and rigidly lock the bracket in position upon the same. These inclined surfaces 6 are so spaced apart from the extensions 5 that the latter will engage the inner surface of the channel bar before the lugs 4 reach the bottom of the T-slots whereby any wear, variation of the thickness of the bar, or other slack will be automatically taken up by downward pressure on the bracket, thus insuring against any looseness of the bracket upon its support.

The whole structure is very simple, easily manufactured from sheet metal by dies and requires no bolts, screws, or other like appliances, at the same time being effectual and satisfactory in operation.

That I claim is l. An adjustable bracket comprising a channel bar, having T-slots at regular intervals, a bracket having an end provided with surface inclined to the plane of the bar, lugs on the bracket to extend through the vertical portions of the slots, and oppositely proj ecting horizont-al extensions on the lugs to pass through the horizontal portions of the T-slots and forced into engagement with the inner surface of the bar by said inclined surface.

2. A bracket comprising a channel bar having T-slots and a sheet metal bracket having two lugs to extend through the vertical portions of two of the slots and also having an end surface below each lug inclined to the plane of the bar and an extension at the top of each lug bent horizontally to pass through the horizontal portions of the T- slots, the respective extensions being bent in opposite directions, from the plane of the lugs.

3. An adjustable bracket made of sheet metal comprising a sheet metal channel bar having a series of T-slots at regular intervals and a sheet metal bracket having lugs to extend through the vertical portions of the T-slots and vertically slidable therein also having oppostely bent horizontal eX- In testimony whereof ll my signature tenslons at the top of the lugs to pass 1n presence of two Wltnesses.

throuo'b. the horizontal portions of the slots and slldably engage tbe inner surface of the ANTHONY VANDERVELD' bal, said bracket also having an inclined enel VitnesSes: sul'faoe below each lug to engage the outer PAmtnR A. JONES, surface of the bal". LUTHER V. MOULTON.
